Acoustic Safe

The device was developed by PROFISEC Ltd. The purpose of the acoustic safe is to block the audio access of a GSM phone to the conversations in its physical environment. In meetings and confidential conversations it is important to take precaution against eavesdropping via GSM devices. The jammers are a good decision, but they affect to the other phones at the office or area. Furthermore there is no decision if somebody expects an important call while using a jammer. The jammers are not affecting the built-in the GSM device dictaphones.

The acoustic safe blocks the GSM microphone by creating white noise. When a conversation begins the GSM devices have to be placed at the acoustic safe, the white noise generator to be switched on and to close the safe cover. In that way the GSM phones don’t have audio access to the conversation and it is not possible to record it on the GSM dictaphone or to be intentionally relaying or as a result of a spy software. In the same time people can be called on the GSM phone and react if they wait important information. The acoustic safe usage doesn’t require leaving the phones outside the room, their exclusion or removal of batteries. The acoustic safe successfully counter against built-in additional microphones in the mobile phones.

The Acoustic safe can also prevents eavesdropping via IP landline  telephones (additional option).

The device works with built-in standard or accumulator batteries, or power supply.

The Acoustic safe can be made in different sizes/ colors (to comply with the interior), with transparent lid or EMI shielded (Faraday Cage). In this case the devices in the Acoustic safe are completely blocked and they are not connected to the mobile network.
